NH Research 4760-6-AUX DC Electronic Load

Overview

The NH Research 4760-6-AUX is a 6 kW programmable DC electronic load designed for high-power testing applications. It provides voltage and current control with a unique Auto Mode that enables glitchless automatic switching between constant resistance (CR), constant current (CC), constant voltage (CV), and constant power (CP) limits. The load is engineered to operate reliably under demanding conditions and can be configured for single or parallel operation.

Key Features

• 6 kW power capacity, 300 A maximum current, 600V voltage range (7.0 - 600V)
• Auto Mode for glitchless switching between CR, CC, CV, and CP control modes
• High-speed waveform capture at 100 kSamp/s with overshoot, undershoot, rise-time, fall-time, and settling-time measurement
• 100-step macro recording for capturing and replaying complex, multi-mode load profiles
• Modular design with synchronous control and active power balancing for parallel operation
• Multiple control interfaces: manual touch-panel, emPower test executive, and PC/LAN control via LabVIEW and IVI drivers
• Test fixture support with 4 digital outputs and 2 digital inputs

Applications

• Fuel cell and battery testing
• Power converter and DC power supply testing
• Telecom rectifier testing
• Vehicle to Grid (V2G) system testing
